Struct tray_rust::bxdf::specular_transmission::SpecularTransmission

pub struct SpecularTransmission<'a> { /* fields omitted */ }

Specular transmission BTDF that implements a specularly transmissive material model

Methods

impl<'a> SpecularTransmission<'a>

pub fn new(c: &Colorf, fresnel: &'a Dielectric) -> SpecularTransmission<'a>

Create a specularly transmissive BTDF with the color and Fresnel term

Trait Implementations

impl<'a> BxDF for SpecularTransmission<'a>

fn bxdf_type(&self) -> EnumSet<BxDFType>

Get the type of this BxDF

fn eval(&self, _: &Vector, _: &Vector) -> Colorf

We'll never exactly hit the specular transmission direction with some pair so this just returns black. Use sample instead

fn sample(&self, w_o: &Vector, _: &(f32, f32)) -> (Colorf, Vector, f32)

Sampling the specular BTDF just returns the specular transmission direction for the light leaving along w_o

fn matches(&self, flags: EnumSet<BxDFType>) -> bool

Check if this BxDF matches the type flags passed

fn pdf(&self, w_o: &Vector, w_i: &Vector) -> f32

Compute the pdf of sampling the pair of directions passed for this BxDF

impl<'a> Clone for SpecularTransmission<'a>

fn clone(&self) -> SpecularTransmission<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
